How do I get rid of the rust on my knife?

:(

I've really neglected it. any advice?

[Babelfish]

You could try steel wool. Be warned that if you use coarse stuff, then the finish will get all scratchy looking. In order to keep the finish nice you will have to go over it again with finer grades of steel wool, in order to get that nice polish back. But, if you don't care that your knife has a dull (brushed) look, then go ahead and steel-wool it.

You can also get some wire-bristle attachments for a Dremel tool. Just be careful not to wear down any spots too much.

When you're finished put some of that silicon grease on it that they sell at the local dive shop. Otherwise it will just get rusty again.

Whenever you work on a knife, make sure it is secure. Clamp it to a bench if you have to. Be safe!

i wouldnt advise a steel wool but that realy depends on the steel and surface type,

at the machine shop after removing harden steel from the wire edm solution the medal would almost rust in seconds with out a protected surface like either stainless finish or solid stainless steel wich consist of mostly nickel in wich theres not much you can do but...


if the steel has a powder coat and is not stainless you may not want to remove the powder coat with a wool cloth,

try a strong toilet bowl clearer like lysole (may be misspelled) lol another one!!!

but after you use that on it by rubbing it with your fingers for a few moments youll have to use baking soda to nuetralize the acid
very important or the toilet bowl cleaner will continue to eat the medal in time

hope it work, dont worry its safe and non harmfull if it doesnt hurt

Well, this may be a bit out of control, but here is two options. Soak the knife in CLR, available at walmart and I think supermarkets.It will dissolve the rust. The second....... Dry sand the blade w/ 220 paper. Then wetsand with 400, 600, 800 and 1500. Then hit with mechanical buff (orbital sander with polishing bonnet) and good metal polish ie, mothers, busch (best), flitz etc. It'll come out like chrome. I do a lot of car restorations and this is what I've found to work best.

good luck

CLR is awesome stuff. They sell it at most hardware stores, and I think someone mentioned WalMart too. It stands for "Calcium, Lime, Rust". It is used for cleaning up hard water deposits in your bathtub.

Poor knife!
No neglect = No rust.

Babelfish,

Thank you, I'm going to pick some of that up and get rid of some of my own rust.

whatever method you use, make sure you put some silly cone.... silicone.. on in after.... best protection....

1. Soak it in Coca-Cola Classic a couple days.
2. Hot fresh water rinse
3. Oil it with an organic oil (Citrus, vegetable, lard, etc)

Fish smell synthetic oils, and tend to depart the area.

Its kind of like a comet (cleaner) or something like that.

The Coca Cola idea is a little scary - especially if it works!!! ;)

[kwesler]

I have used WD-40 and a little steel wool

Ospho is an industrial product and Naval jelly is a home depot type product. They both contain phosphoric acid, as does coca cola. Use either of the two products for your knife. They both have warnings about ingestion. The coke does not.

LPS III is a coating similar to CRC or WD 40 but it leaves a waxlike coating behind. It's a great rust preventative.

[cwinston]

I've used the Coca-Cola trick in the past and it works well, it also does a good job of taking the wax off your windshield after you go through an automatic car wash. Collectors will frequently drain their coke cans before storage because in a few years it will eat right through the can.

[oversea]

coke has many uses. Cleaning Rust, cure upset stomach, put a steak in a pan of coke and in a few days it will dissolve. Local police keep it, as it cleans blood stains from the street. There are more but can't remember all.

[Scythaxe]

Try to use dish-sponge with mild abresives on one side and -believe me or not- oil the knife with your nose-oil (that is what pipe smokers do to their pipes making their pipes shiny) You will see that it works better than any silicone grease:))

[ShoalDiverSA]

Scythaxe,

You must be joking! Nose-oil! :puke:

How do you get the knife oiled without committing hari-kiri?

Andrew.

[Scythaxe]

Pls excuse me for my bad english...I mean the oily skin of your nose Get the oil of your nose skin and oil your knife with it.(I think this time I explain what I mean..or don't I):)

[ShoalDiverSA]

Phew!

Thanks for clearing that up. I will now be able to keep down my supper tonight - the mental image will not haunt me... :ghosty:

Cheers,

Andrew

Go to a marine store and buy a can of Never Dull its is a safe polish that removes rust and other bemishes, it might take a few times but it will remove the rust.
:D

[pipedope]

As it tends to leave microscopic bits of steel that rust very quickly.
Bronze wool or stainless steel wool are OK

WD-40 works great for rust stains.
If you spray WD-40 every few dives, then the knife will keep almost rust free.

Actually I got a little tired of doing that, so bought a Ti knife, and now I just chuck it after a freshwater rinse. :D

[oatmeal769]

I got so tired of cleaning and oiling my knife every day. I switched to EMT shears as my cutting device, and love them. I find they stand up to rust better, and when they do get so corroded as to not work, I just toss them, and get a new pair. They're easy to find, and always less than $10 bucks.
Plus, if you drop or lose them, you aren't out the 50 or 60 bucks to replace a dive knife. They travel better too, some airports will give you grief over a knife. I keep a spare set in my dive bag.

Hello,

The short answer is you don't get rid of 'rust', i.e. iron oxide. Wise man once said if you want to keep anything then don’t put it in salt water. When a knife rusts you loose structural integrity and it's a downhill spiral from there. All you can get to is the surface rust and make it more appealing but you can not get to the subsurface rust. The easy and best answers is put it in file 13 then go buy one that has great rust resistance or one that does not rust at all.

By using all these mentioned chemicals and methods you are just prolonging the inevitable, besides when that one day comes you have to use it and the knife fails.. well you get the idea.

I didn't have a problem with knives rusting because I lose them - nothing else - just knives. I keep my EMT shears on a short length of bungee cord stuck in a little piece of plastic tubing clipped to my backplate. I bought a UK Remora a few months ago for my waistband and have miraculously managed to keep it - whatever it's made from, it sure is rust-resistant.:sharky:
